That's screwed up total disrespect. Then some wonder why non motorcyclists think some of us are assholes...imho
This is an old joke, but it really amuses me: A man enters a spare parts warehouse and says «please, give me a 710». The dealer answers «what's a 710?» and the man replies «it's a part of my car; it's like a knob and it has "710" written on its centre». The dealer really doesn't know any part like that, so he says «well, if I open the bonnet, will you be able to recognize it and point at it?» «sure!» replies the man. So, when the dealer opens the hood, the man says «here it is!».
